Specification of Letters Patent. Patented June 27, 1911.

Application filed September 21, 1910. Serial No. 583,046.

Be it known that I, JOSEPH J. STooKER, a citizen of the United States, and resident of St. Louis, Missouri, have invented Certain new and useful Improvements in Blowers,

V of which the following is a specification.

This invention relates to improvements in blowers and has for its object a casing in which is mounted a revolving member, the casing beingso constructed as to receive and carry all of the air from the bottom of the revolving member, the upper portion of the casing so arranged as to permit the revolving member to operate freely and ineffectively.

A further obj eot of my invention is to provide a revolving member arranged to operate on a. stationary shaft, a shield mounted rigidly on the shaft inclosing the upper, inner portion of the revolving member, its one end being pointed so as to eliminate the greater portion of the humming caused by the rapid revolution of the revolving member, and a lower casing so constructed as to receive the air, and an additional spout for taking care of the air which is carried past and not admitted into the lower receptacle proper.

This invention is an improvement over applicants patent issued to him July 12, 1910, No. 963,957 for blowers and the most essential feature of the improvement lies in a construction of casing and pointed inner shield to eliminate the greater port-ion of the noise created by applicants former invention, and to gather and utilize all of the air pressure created by the revolving member.

Figure 1 is aside elevation of my complete invention. Fig. 2 is a vertical, sec- 4 tional view of the same taken on the line 22 of Fig. 3. Fig. 3 is an end view of the same. Fig. 4 is a cross sectional View taken on the line 4-4 of Fig. 5, and viewing the same in the direction indicated by the arrow. Fig. 5 is a top plan view. Fig. 6 is a detail perspective view of the butting end of the auxiliary spout made use of in gathering and conveying to the delivery end of the ma chine that portion of the air which fails to enter the air chamber proper. Fig. 7 is a detail perspective view of the shield made use of inclosing the upper inner portion of the revolving member, and for eliminating the greater portion of the humming created by the revolving member.

In the construction of my invention I provide a suitable base plate 8 on which is mounted a casing 9 so constructed as to act as an air chamber for the reception of the compressed agitated air caused by the rapid revolution of the revolving member 10. On

the base plate, and on each side of the casing are rigidly supported supports or standards 11, which are provided with supporting heads 12 in which is supported and rigidly retained in position a tubular shaft 13, the same being provided with openings 14, which communicate with like openings 15 formed in the caps of the supports and through which oil is admitted into the hollow shaft. On this shaft is mounted the revolving member 10, which consists of a pair of rings 16, each having integral arms or spokes 17 terminating at the center in a hub 18, said hubs provided with sleeves which snugly fit over the tubular shaft, and on said sleeves are rigidly mounted pulleys, by which the revolving member is rotated.

The tubular shaft 13 is provided at its bottom with small apertures which communicate with the hubs and sleeves and are for the purpose to permit the oil which is inserted into said shaft to continuously lubricate that portion of the revolving member which operates on the shaft. This construction is clearly shown in Fig. 4 of the drawmgs.

In the space between both of the rings 16 and at suitable intervals apart are firmly riveted, or otherwise secured, a plurality of curved agitator blades 19, the relative position of said blades being clearly shown in Fig. 2. The agitator blades or paddles, as arranged between the two rings are of two sizes and are arranged alternatively, one long and one short. The object of the short paddles located between two of the long ones is to divide the outlet space between the same and assist in gaining a greater agitation to the air. The connection of the spoke 17 to the rings 16 is such as to provide an offset or that by this formation the greater portion of the humming caused by the rapid movement of the revolving member is ellmmated.

Connected to the casing 9 and located over the upper portion of the revolving member is a hood 26 consisting of a flat sheet of metal 27 held rigid by the stiffening ribs 28.

On the discharge end 29 of the casing 9 is attached the delivery spout 30 through which the agitated air is conveyed to its desired destination. On the top of the discharge end 29 and immediately in front of the revolving member is located a casting 31 which acts as the butting end of the auxiliary spout 31 by which said spout is firmly secured, the discharge end 33 of the auxiliary spout communicating with an opening 34 formed in the upper end of the spout 30. It will be observed that the auxiliary spout 32 is of curved construction and that its passage way is tapered in form, the greatest end being its inlet, and located immediately in front of the revolving member, and its purpose is to catch and convey that portion of the air agitated by the paddles or agitators, between the point 35 of the casing 9, and the point 36 of the auxiliary spout. It has been discovered by continuous experiment that a certain amount of agitated air is lost by striking the solid wall of the housing between these two points.

The space between the shield 22 and the hood 27 is what applicant terms a dead passage. The paddles or agitators while traveling through this space are performing no function as no air is admitted into this space. The only operative portion of the revolving member is that extending into the casing 9 and in front of the auxiliary spout 32. The air is admitted through the center and the centrifugal force of the revolving member has a tendency to throw off the air on a direct line from the paddles or agitators into the air chamber of the casing 9.

The rear portion of the casing 9 as indicated by the numeral 37 is of greater depth than the remaining portion of said casing and acts as a pocket for the free reception of the agitated air, the volume of air in said pocket forming a cushion preventing a back pressure of said air into the revolving member.

Having thus fully described my invention, what I claim as new and desire to have secured to me by the grant of Letters Patent, is:

1. A blower of the class described com prising a revolving member, a casing mounted below the revolving member, a shield having one end tapered located rigidly within the revolving member and an auxiliary spout leading from the periphery of the re volving member to the outlet of the casing,

substantially as specified.
